    or kS/s

    kilosamples per second, or thousands of samples per second

  • SPS

    millisecond, or a thousandth of a second

  • us

    microsecond, or a millionth of a second

  • ns

    nanosecond, or a billionth of a second

  • I2C

    Inter-Integrated Circuit

  • SPI

    Serial Peripheral Interface

  • SWI

    Single Wire Interface (Atmel)

  • CAN

    Controller Area Network

  • HDLC

    High-level Data Link Control


    High-Definition Multimedia Interface Consumer Electronics Control

  • I2S

    Inter-IC Sound

  • PCM

    Pulse-Code Modulation

  • JTAG

    Joint Test Action Group

  • LIN

    Local Interconnect Network

  • MDIO

    Management Data Input/Output

  • MIDI

    Musical Instrument Digital Interface

  • SMBus

    System Management Bus

  • SWD

    Serial Wire Debug

  • UNI/O

    (not an acronym), a protocol made by Microchip


    Universal Serial Bus Low Speed / Full Speed

  • Baud rate

    data rate measured in bits per second

  • MSB

    most significant bit

  • LSB

    least significant bit

  • Parity

    additional information added to the data to provide error detection information

  • Processing backlog

    In the Saleae software, the data recorded from the device is transformed to the storage format as it is recorded, in near-real time. If the process is unable to keep up with the recording in real time, the processing backlog will grow as unprocessed data are buffered.

  • Trigger backlog

    In the Saleae software, when the trigger is used, the processed data are then fed into the trigger in near real-time. If the trigger thread is unable to process the already transformed data in real time, the trigger backlog will grow as processed (but not yet searched) data are buffered.

  • MHz (Megahertz)

    Millions of cycles per second. It is a measure of frequency, usually in reference to bandwidth.

  • Protocol Analyzer

    A software plugin for the Saleae software that will decode standardized signals into bytes.
